Abstract
To test three recruitment strategies for parents on social media (Facebook and Twitter) to complete a brief survey about the human papillomavirus (HPV) vaccine. Methods: We created three campaigns with ads on Facebook and promoted tweets on Twitter that invited parents of children ages 9–15 to complete a brief survey about the HPV vaccine. Iterative, yet varied, campaigns were conducted to determine the ideal social media platform, compensation amount, and messaging. Ads depicted vaccine-eligible children (11–12 years of age) of various ethnicities. Ad messaging was adapted from social media toolkits at the CDC and the HPV Roundtable. Parents who clicked on our ad were first screened for eligibility. Those who were eligible then completed a 20-item survey via Qualtrics that included questions about HPV, the vaccine, and social media use. Survey compensation was either $5 or $10. At the end of the survey, we provided information about HPV and the vaccine. The campaign was available in English and Spanish. Results: The first campaign was launched on both Facebook and Twitter and offered $5 compensation. The Facebook component yielded 18,527 impressions; two adults were confirmed eligible by the screener and both completed the survey (100% screener to completion rate). Cost per survey was $349.45. The Twitter component received 143,661 impressions and yielded 18 completed surveys, with a screener to completion rate of 26% and a cost of $42.99 per survey. For the second campaign, we dropped Facebook and focused solely on Twitter, offering $10 compensation. We received 50,475 impressions that yielded 55 completed surveys (screener to completion rate = 71%) costing $4.78 each. The final campaign tested simpler messaging on Twitter with $10 compensation, and received 8,897 impressions, 38 survey completions (screener to completion rate = 88%), and cost $1.19 per survey. Conclusions: While Facebook is widely used among Americans, our findings may suggest that Twitter is more engaging and cost-effective. Recent Facebook policy changes may explain the differences seen in cost and survey completion. Understanding the reach and effectiveness of the different platforms will help ensure the success of an intervention using social media.
